Why UMC stock is down today
United Microelectronics ADR (UMC) fell 9.75% to $17.22 in early trading on Tuesday. The sharp decline followed a 13.1% gap down from the previous close at $19.08. The stock has been under pressure amid recent insider sales and a broader sell-off in the technology sector.
What Happened
UMC opened at $16.59, marking the lowest point of the session at $16.11 before recovering slightly. The stock is now trading near the bottom of its 52-week range, which spans $6.56 to $28.96. The decline comes after two recent insider transactions, including a sale by the CFO, Liu Chitung, and a VP, Hu Che-Jen. These sales totaled $296.0 million over the last 90 days, with no insider purchases recorded in that period. The stock has also declined by 14.4% over the past eight sessions, reflecting ongoing investor caution.
What The Data Shows
UMC is trading at a high price-to-earnings ratio of 153.2, despite a trailing 12-month revenue increase of 2.2%. The stock has a beta of 1.57, indicating higher volatility than the broader market. With a market capitalization of $49.7 billion, UMC has a net margin of 20.8% and a dividend yield of 1.62%. The recent session saw a volume of 2.5 million shares, which is 0.2 times the 3-month daily average. The stock is currently down 38.9% from its 52-week high.
What To Watch
UMC is scheduled to pay a dividend of $0.315608 per share on July 8, 2026. Investors will also be watching for further insider activity and any developments in the company's gross margin performance, which is expected to rise due to increased utilization.
